摘要：
A hybrid topology optimization (HTO) method is used for the design of patch antennas with symmetry. The scalar isotropic material with penalization (SIMP) and the level-set method (LSM) are combined together to form the HTO. By applying the hybrid scheme, a conical beam patch antenna and a two-element MIMO antenna are optimized. For the conical beam antenna, the topology of the patch and the existence and location of the vias are optimized simultaneously. For the MIMO antenna, only the isolation structure is optimized. In order to decrease the optimization complexity, the symmetry of the antennas are utilized and only parts of the structures are optimized. The performances of all the antennas are verified by the simulation and measurement.
